Geometric Optics

Geometric Optics is a super easy-to-use and fun little app that runs on Java. It helps you see how a lens projects an image of an object. If you're into physics or just curious about optics, this tool is great for you!

Getting Started with Geometric Optics

To get started, you'll need a compatible browser. The app requires both Java and Adobe Flash Player. Once you've got those installed, the program will run in a special HTML file right in your favorite web browser.

What Can You Do?

This app shows you an emulated object, the lens, and how the object's image looks when projected. You can move the object around to see how it changes with different refractions and curvatures. There’s even a handy control panel where you can tweak the lens and object settings!

A Great Learning Tool for Students

The coolest thing about Geometric Optics is that it helps students in cinematography and physics understand camera obscura optics. You can explore how different lens shapes, refractive indices, and diameters affect image projection.

Interactive Features

You can make things interactive by selecting or deselecting projection rays. Move the lens around or adjust the projected object as much as you want! If one point of projection isn't cutting it, you can enable a second point for a detailed view of how light rays hit the screen.

Share Your Findings

Once you've finished your simulations, feel free to upload your data to PhET's official website! They have tons of similar Java-based simulators that you can check out and test out for free.

An Educational App Worth Trying

Geometric Optics is a fantastic little app designed to simulate projections like those in a camera obscura. You can change properties like lens diameter, refraction index, and curvature to make this program perfect for educational purposes! Ready to give it a try? Download Geometric Optics here!
